Jo "aZZ whom it may concern:

' Be it known thatl, Nii'i nAN J. GOLDFARB, a citizen of the UnitedStates, residing at New York in the borough of Brooklyn 1, 1 7 I v 1 7county; of Kings, and State of New Your, have invented certain new anduseful Improvements "in AddingeMachines, of-which .the' followingis aspecification.

- This;inventionrelates to adding machines,

and more particularly to the type of machines f described in- LettersPatent No. 844,120 granted ine under date of February 12, 1907.

The. invention aims to improve the general I 7 construction of themachine described in this flnli o.

Afurther object of the invention is-to provide a machine having anitemizing attach-. -ment bylmeans of which certain columns patent, andparticularly the carrying mechmay be used to automatically register thenumber of. items added in the other columns.

This itemizing device is, so arranged that upon every actuation of'thecarrier-energizing bar vhich precedes every addition, the

numeral carrying elements of certain columns willbe actuated by thisbar, so that the total number of items added by the machine will appearwith the result of the addition.

Theinvention also aims to provide a checkmg device for the chainsemployed, by which the latter are prevented from running toofar whenactuated. This device serves to lock t I, the chains after eachactuation, and thereforealso serves as a reminder that thecarrier-energizing bar must be actuated, said tion of this ar. Y

:40, ting device whereby, when the numeral-can rying elements-are settoi-zero, the carriers will at the same time be automatically releasedby thefohecking or locking mechanism, and soconnected with thezero-settingr de vice: as to belenergized and' carry the elements tozero. Thus the carrying mechangi -m5 aids the zero-setting mechanism and-causes all of'tlie numeral carrying elements to be simultaneously movedto zeroposition.

"This additional function of the carriers also serves tocause alltheelements to be pro erly and uniforml set to zero, which won d nototherwise be t 'e case if certain ofthe carrierswere'released at the endof the addition. Without this connection of the zerosetting mechanismwith the carrying mechanism, by which all the carriers are energized andactuated at the proper timc, the carriers which remain energized wouldcarry those which are not energized from 0 to 1 when setting to zero.

The invention also contemplates the provision of zero-setting devicewhich-acts on "the chaln wheels which are at the front of the claimed.

11 its main features the present machine" is constructcd on the lines ofmy atcnted machine heretofore mentioned. t conirises a casinglO havingan inclined front- Eace' provided at its upper part with the usualapertures over the number-wheels. It also has a numher of parallel slotsin which the chains 11 move over a glass cover-under ,which the numbersare arranged on a suit- The carrying mechanism is located bc- I neaththe chains and ad acent the number'- wheels '13.- Each number-wheelcarries at one side a pin 16 which-coacts withone arm. of a trigger 17.One trigger is mounted in each compartment on a shaft 18 which ex-'tends-through the partitions, being pivoted to swingon said shaft andacted upon by a small; spring 19 holding it in position after engagingwith the corresponding pin 16 on the number-wheel. The said trigger ispreferably, stirrup-shaped, as shown 1n Fig. 8,

and is disposed in two compartments, so

that when its arm is engaged by the pin 16' the trigger will release thecarrier in the adj acen t compartment.

The carriers 20 are of substantially U- shape and pivoted on a shaft 21extending parallel to the trigger-shaft '18. Springs 22 coiled about theshaft 21 normally press the carriers in upward direction toward thechains 11. At the upper part of each carrier there is pivotedspring-actuated dog 23 having aprojection 24 which enters the links ofthe corresponding chain, so that when the carrier is moved upwardly. thechain will be actuated and move its numberwheel to the extent ofoneunit. The triggers 17 coact with the carriers 20 by means ofextensions 25, one of which is carried by each trigger. Each such,extension has a notched end 26 coacting with a shoulder 27 formed at onesideof the carrier in the leg thereof, as shown in Fig. 8. In thismanner the carrier may be held in its lowermost position,-as shown inFig. 2, until the pin 16 of the number-wheel in the adjacent compartmentstrikes the trigger, whereupon the extension 25of thelatter 1n beingmoved upwardly releases the carrier, as shown in Fig.

2 and permits the latter under the infiu-.

ence of its spring 22 to actuate the chain and number-wheel.

At the points where the pivoted dogs of the carriers engage the lowerruns of the. chains, the latter are guided over a plate 28 extendinglongitudinally of the machine through the casing.

chain opposite the dogs so that the chain runs between the plate anddog, the proper engagement of'thc latter with the chain is insured. VFor the p n-pose or energizing or setting the carriers, acarrier-setting bar, 29 is employed.

connected by means of connecting rods 31 with levers 32 pivoted on ashaft 33- extendmg through the partitions. The levers 32 operate inslots 34 at the lower front part of v the casing and are connected by abar 35 extending across the front of the machine. It is obvious thatwhen this bar is depressed the carrier-setting bar 2.) will be movedforward, by the connections described, in order to set the carriers.then the operating. bar is released, the parts are returned by thesprings 29 A ratchet mechanism 36, 37 is arranged in connection with oneof the levers 32 in order to insure a complete depression of theoperating bar 35. V

In order to )revent the ovcrrunning of the chains, the fol owingmechanism is em loyed: Each chain travels over a roller 38 coated in thebight of. the chain and coacting with a small roller 39 which is mountedon a pivoted arm 40 acted on by a spring 41 in such a manner that theroller 39 is pressed into the links of the chain against the largersupporting roller 38. The carrier 20in the same vcompartment is providedwith a tongue 20,

which after the carrier has been released by the corresponding triggerpresses on the roller 39, as shown inFig. 2*, so that said roller isfrictionally held. against the chain and causes the some to come to stopat the proper point. This frictional locking device may be used alone orin conjunction with a positive locking device, two devices for thispurpose being )rovided so that if one gets out of order the ocking willstill be effected by means of the other. The positive locking de'viceisformed by a projection 25 extending upwardly from the extension 25 ofthe trigger. When the latter is thrown upwardly and released from thecarrier said projection 25 will take into one of' the chain-links andabut against the guide-' plate 28, as s further movement of thechainis.positively' prevented. These locking devices also serve as areminder that the carrier-setting bar must again be actuated beforeanother actuwn in; Fig. 2, whereby the ation of the machine. When it isseen that the chains are locked the 'carrier setting bar is actuated andthis causes the release of both locking device s. As each carrier-isreturned toset position, as shown in Fig. 2, its

ztongue will be moved away from the lockingroller 39, and trigger 11inbeing moved into set position Will release its projection'frornthechain.

cutaway portion 48 of the gear 48.

v the LnumbeL- wheeis age pulled into zero posit-1on, instead of.Beingpushed as IS -cu'st'omary, is of considerable A The gea'r48 carriesa pin 51 which tits into arslot 5-2 formed in one end of a connectingrod 53 secured at its other end to the lever 32 at the same side 'ofthemachine. The

said connecting rod 'forms an automatic con-' nection between thecarriersetting mechanism and the zero -sett1ng mechanism by which whenthe number-wheels are set to zero the carrier-setting mechanism isoperated. I. It is apparent that before themachine can "be set to zerothe locking devices here-- inhefore described will have t-e be releasedfrom the chains, and'this necessitates a de- .press on of the operatingbar 35 of the car- -nor-setting inechanisin. This is produced by meansof'the connection between the connecting rod 53 and the gear '48. itsthe zero-setting mechanism must remainfinoperative until after thedepression oft'he operating bar 35, the gear 48 is mutilated, havinganumber of teethcut away at 48 and this cutaway part is engaged by. atooth 4:7 on the gear 4-7 Thus the movement of the geare'S which-istransmitted by means ofthe connecting rod '53to the lever 32, is nottransmitted to the gears-A7, 4-6, 45 and shaft 14 until the lever 32 hasheen depressed and theytooth MP-arrives at'the end of the As soon as theteethof the gears 47, 4S;engage each other in the ordinary way the shaft14 will be rotated vand 1 the number-wheels thereby set to zero, asbefore indicated. T he action of the stop 45 and spring 45 with respectto the shaft. 14 is aided by the connection of the zero-settingmechanism with the carrier-setting bar 29. It is obvious t-hatthe levers32 are normally pu l led 'i-n upward position by the springs of thiscarrier-setting bar, and the connection between one of the levers 32 andgear 48 is made in such a way that after the release of the hand-crankthe said'lever 32 will be moved upwardly to a certain extent undertheinfluence of the spring-actuated carrierse'ttingber, so that throughthe train of gears the shaft: 14 will be moved backwardly to a slightextent. Thus the notches ofthe cams ,are moved slightly away A from the,

pawls, as before indicated.

The connection between the zerosetting device and the carrier-settinghar causes the carrying medhanism to be coupled with the zero-settingmechanism-in such a manner as to aid in operation of the letter;vThrough theconnections described, .when the 'zerosettingh'alnd-crank'fifl is operated, the levers {:32 aredepressed, whereby thecarrier-setting bar: 2-9 is pulled down'and sets the carriers and thenthebaris moved back to its initial position. The release of the chainsiseffected 1n the man'ner described. end hy the op'eration of the shaft14 the chain-wheels are carried along from their vaiio'us positionsuntil item, the number-wheels at the left of the the number-wheels allreach the number 9, whereupon, upon a i'urther actuation oi the hand-crank 50, the pins on the number wheels will engage their respectivetriggers, causing all the nmnber-wheels to be carried to 0 instead ofbeing pulled intothis position from 9. s

In adding machines of this type, when cer tain of the carriers remainenergized at the end of the adding operation, these carriers usually actupon their number-wheels, when the machine is set to zero, in such amanner that the latter will be carried from (Ho 1, so that whilst)appears through certain apertures in the casing, 1 appears throiighother of such apertures. By the connection with the carrying mechanismhereinhefore described this isobviated, as all the carriers areenergized at the same time automatically by the operation of thezero-setting hand-crank and then released to permit the carrying of thenumber-wheels to their zeroosition. Thus the uniform movement of all t enumber-wheels to zero is produced.

One or'more of the columns at the lefthand side of the machine may beutilized for the addition of the'iitems addedby the columns on theright.- To this end an itemizing device is provided whichisautomatically operated by thecarrier-setting mechanism so that when thismechanism is operated, which is necessary after every addition of anmachine will be so actuated as to register thenumber of items so added.This is caused by means of keys 54, of which one is used "for eachcolumn utilized for adding items, -these keys, of which two are shown,

being mounted in the casing directly above the it'einizing columns.'Each key 5 1 has cprved lower end engaging with the correspondingItrigger 17 at the intermediate part of the latter, and by depressingsaid key said trigger may be moved sli htly, but to In the machineillustrated two columns at the left of the machine are used foritemizing purposes. I The two depressihle keys 54 are connected beneaththe cover-plate of the easing by means of apivoted lever 56 in such a,

manner that only one of the itemizing col umns may be used at a time,one key. being in its up erinost position while the other is depressor.The lever 56 is held in position by means of a catch 57.

It sometimes happens that when the chains are pulled down to move thenumberwheels to 9 the shock will be great enough to cause the chains andtheir wheels to overrun, thus producing the abutment of the pins 16 withtheir triggers and causing the carrying.

At first of the number-wheels to zero. glance-it might appear that thiscould be overcome by moving the pins 16 back on their wheels to acertain extent. But when this is done and the carrying takesplacc atpivot and being located one within the other Each number-wheel is on thesame shaft. provided'with the usual pin 16, which first coacts with theinner spring-actuated trigger 58 and then with a second outerspring-actuated trigger 59. The extension 60 01 the inner trigger 58 isprovided with a shoulder which engages with the.carrier in substantiallythe same manner described in connection with Fig. 8, and the outertrigger 59 has a similar extension 61 having a similar shoulder, which,-however, is held behind the shoulder of the trigger 58 in such a mannerthat the latter shoulder will first engage the carrier, the shoulder ofthe other trigger be ing out of engagement therewith.

' The upwardly extending arm of the trigger I 58, whi h s rikes the pin16, is of the'usual form, but the upwardly extending arm of the outertrigger 59 is made hook-shaped, as shown, so that when the pin strikesand actuates said trigger it will remain in contact with the end of thesame, as shown in Fig. ,1().

' The-operation oi this mechanism is as follows: The pin 16 firststrikes the inner trigger 58, and as this trigger is entirely pendent ofthe trigger 56 it will be mt. a certain extent, independent of saidtrigger 59, into such position that its shoulder will releasethc'carricr, whereupon the carrier will move upwardly to a slight extentuntil it ongages with the shouldered extension 61 of the trigger 59.shownin dotted lines in Fig. 9. Upon a further movement of thenumber-wheel and "its pin the latter will engage the upwardly extendinghooked end of the trigger 59 and said trigger will be rocked into theposition shown in Fig. 10, thus releasing the carrier and permitting itto advance the chain and corresponding number-,wheel. I

It is understood that the pin 16, which is merely indicated in dottedlines, is carried This position of the parts is by a number-'wheellocated in advance of the one illustrated in Figs. 9 and 110':

As before indicated, when the carrying 0 eration has taken place thepartsassume t e position shown in Fig. 10', in which the hooked arm ofthe triggerf59 is stil'l in engagement with the pin 16 It is apparentthat while in this positionthe trigger 59 cannot be engaged with .thecarrier when; the carrier-setting bar is pulled against the latter"However, the carrier isset. by means of'the trigger 58, which is in posito'set the'same;

tion to properly engage the carrier, said trigger being independent inits movement of the trigger 59L- Hence the inner trigger acts as asetting trigger, while the outer trigger acts as a releasing trigger torelease thefcarrier at the very last moment, so that v remature'carrying will not takeplace; pona further movement of the number-wheelthe pin 16 will move beyond the trigger 59, whereupon the parts willagaintake the position shown in Fig. 9.
